A method may be for controlling communication between a UICC, a handset including the UICC, and an external device associated with an external application running outside the handset. The method may include switching on the UICC by the handset, executing a first initialization procedure by the handset to establish a first communication session between the handset and the UICC, establishing a second communication session between the UICC and the external device, and executing a second initialization procedure between the external device and the UICC. The method may include retrieving an attribute of the handset by the UICC after completing the first initialization procedure, retrieving an attribute of the external device via the handset by the UICC after the completing the second initialization procedure, and comparing the attribute of the handset with the attribute of the external device to distinguish the second communication session from the first communication session.
